Bridge Expansion Joints

Modular Expansion Joint System

MEJS is a mechanical device installed in bridge expansion joint
openings. The primary function of the MEJS is to allow vehicle
traffic to travel smoothly across large expansion joint openings.
It does this by dividing the large expansion joint openings into a
series of smaller openings called cells. These cells work together
to accommodate the necessary thermal bridge movement (expansion and
contraction) while providing a smooth riding surface for bridge
vehicle traffic. The MEJS is normally used for expansion joints
with a movement range up to 960mm. For movement greater than 960mm
please contact our technical department info@usluk.com.

MEJS also has the secondary function of protecting the
surrounding bridge superstructure and substructure. All MEJS cells
are equipped with watertight sealing elements that prevent debris,
water and corrosives such as de-icing chemicals from passing
through bridge expansion openings and damaging superstructure and
substructure components.
